가시영역 하한 근방의 파장 380 내지 400㎚ 정도를 함유하는, LED 광원의 발광 파장 340 내지 500㎚ 정도의 단파장으로부터 적외선 영역의 장파장에 이르는 폭넓은 파장의 고휘도광의 반사율이 높고, 열전도성이 우수하여, 그 고휘도광이 조사되어도 경시적으로 황변되거나 열화되거나 하지 않고, 내광성, 내열성, 내후성, 난연성이 우수하여, 기계적으로도 화학적으로도 안정적이며, 백색인 채로 장기간 유지할 수 있는 데다가, 금속이나 수지에의 접착성이 우수하여, 배선 기판이나 패키지 케이스 등으로서, 간편하게 형성할 수 있고, 생산 효율이 높으며, 저렴하게 제조할 수 있는 범용성의 실리콘 수지제 반사 기재를 제공한다. 실리콘 수지제 반사 기재(10)·(20)는, 3차원 가교된 실리콘 수지에, 그것보다도 고굴절률의 백색 무기 필러 분말(12a)·(12b)이 분산되어 함유된 반사층이, 지지체 상에서 막 형태, 입체 형태 또는 판 형태로 형성되어 있다. Disclosed is a versatile silicone resin reflective substrate which exhibits high reflectance of high luminance light from an LED light source over a wide wavelength from short wavelengths of approximately 340 - 500nm, which include wavelengths from 380 - 400nm near lower limit of the visible region, to longer wavelength in the infra-red region. The silicone resin reflective substrate also exhibits superior thermal conductivity, light fastness, heat resistance, weather resistance, and flame resistance without deterioration such as yellowing caused over time by the irradiation of the high luminance light. The silicone resin reflective substrate further exhibits mechanical and chemical stability, the ability to maintain a white color over a long period of time, and superior adhesion to metals and resins. The silicone resin reflective substrate can be easily formed as a wiring substrate, a packaging case or the like, and can be manufactured at low cost and a high rate of production.The silicone resin reflective substrate (10 * 20) has a reflective layer which contains a white inorganic filler powder (12a * 12b) dispersed in a three-dimensional cross linked silicone resin, the inorganic filler powder having a high reflective index than the silicone resin. The reflective layer is formed on a support body as a film, a solid, or a sheet.
